a: air. WHOM r; ar, CONCERN;

Beitlgnownkthatl, MIcHAEn H, Wnmnr, of Chicago, in the county of Cook, and Stateof ll linois,- have invented a new and useful Improvement in-G'rain Briers; and I do hereby declareand make known that .the 7 following is a full,'clear, an'd'exact description of 'the same, reference being had to the accompanying drawings, and the letters and figures marked thereon,- which form part of this'specif cation." 4 My invention relates to agrain-drying apparatus having-a series of one or more hollow, revolving cylinders, arranged one above another, thrbughwhich the grain passes in successionfrom the upper to the lower one of "the series .as hereinafter more fully described, and it-consists in passing the fire-flue of .the furnace connected .with said apparatus through the said cylinders, substantially as hereinafterv described. My-invention further consists in a no'vel arrangement ofbuokets upon the interior sgpfaces of the cylinders aforesaid, whichcarry the grain up to --the upperpartjof the cylinder, and then discharge it upon, the central shaftheated by the. flue aforesaid, as is hereinafter setforth i 4 4 I i a To enable those-skilled in the art:to construct and use m'y'inveption, I will proceed to describe its construe ltion' and operation'with particularity, ,making reference in so doing'to the-drawings aforesaid, iri whieh- Figure 1 represents a side elevation of my invention. i I

Figure '2, along'itudinal vertical-central section thereof and Figure3, a. transverse section of the same at z lin fig. 1. I

Similar letters of reference inJthe several fignresindicate the same parts of myinvention.

A represents any suitable franie tosup'port the operating parts 'of' my invention, which may be enclosed or not, as preferred. B represents a series of cylinders, arranged one above another, as shown, and having a longitu'dinal inclination in opposite directions, su filc'ient "because the grain to pass from one endto theothsr; as desired:

The Said cylinders are; ittach d to-a hollow shaft, 0, by means of the arms a, as shown, or in anyother suitable nianner, said shafts being supported at each end'npon suitable frictional hearings or wheels, D, upon the crossenpp'orts A at the ends of the frame,'.as shown. The ends of the said cylinders are closed by-stationary heads marked Bl, which are permanently secured to the frarne, the cylinders revolving closely against'said heads, there being suitable openings at the centre thereof to 'a llowthe .hollow' shafts to pass through, as shown. The ends 01 vthe arms a which are attached "to the cylinders are bent back, as shown in fig. 3, and along strip, 6, is attached thereto, forming a shelf onseries of shelves or bucket s, upon which the grain is carried up as the cylinders revolve, near thetop, whence it is'preeipitated iipon tliehet shaft 0, heated as hereinafter set forth.- The required rotatory movement'is given to said cylinders ,by rneans of the gear-wheel F, upon the shaft E, .whieh is revolved by belting upon the drum G, and the spur-wheels H I, upon said hollow shafts C, or .in any other'suitahle and convenient manner. J represents a suitable furnace, havingwa system of hot-air pipes, M, into which the air is forced by any suitable fan or: blower,'and when heated passes into the cylinders B, through suitable openings'in thaheads thereof, to receive-the hot-a pipes. L represents the fire'and smoke flue or draught passage of the furnace, and it is first passed through the aforesaid hollow shaftG of" the lower cylinder, whence it passes in like manner-through the shaft of tho-next cylinder, and so on through the entire series, assing front the upper-cylinder into as'uitable sinolre stack or chimney, 'as desired. By this arrangement, in addition to' the heat produced by the hot-air "pipes, the entire heat from the fire is made available for heating and drying purposes, has'prodncingan'apparatus for'drying grainiatonce cheappsip ple, and economical.

The grain is' intredueed intothe higher end of the upper cylinder, wh'erepmcre than one is used, through a as shown,-'in the head, whence it falls through a ",sui t able hopper, formed upon'the head of the cylinder, below into said cylinder, and seen through theeti es, the-grain during its entirepr'o'gress through the miichin'e being 'r nany times carried up upon the shelves aforesaid-marked b, and dropped and scattered down through the heated air in the cylinder, upoji the revolving heated shaft :0, whereby it is thoroughly scattered and separated seas to greatly facilitate the process of drying 'thesame.
